How do i calculate the torque of an engine?
Torque is defined as force multiplied by the distance, from the axis of rotation, at which such as force is applied.In the case of an engine, I believe the torque would have to be measured.
Does the vector quantity torque depends on the choice of origin?
No, torque is a vector quantity that does not depend on the choice of origin. Torque is defined by the force applied to an object and the distance from the point of rotation, regardless of where the origin is located.
Why does a bar magnet placed in S-N direction turn towards N-S direction when torque acting on it is zero?
If the bar magnet turned then there was a torque acting upon it. Torque is defined as a turning force or moment.
What is meant by torque in ac machines?
'Torque' applies to any motor, not just to a.c. motors. It is a turning moment, defined as distance multiplied by the force acting at right-angles to the shaft.
What is the relation between torque and angular acceleration?
Torque is the rotational equivalent of force and is responsible for causing rotational motion. Angular acceleration is the rate at which an object's angular velocity changes. The relationship between torque and angular acceleration is defined by Newton's second law for rotation: torque is equal to the moment of inertia of an object multiplied by its angular acceleration.
What are torques?
Torque is a force that is applied to a lever. (Imagine a rachet. As you tighten a bolt, you push on the handle, which is essentially a lever. This lever exerts torque on the bolt, causing it to spin) Torque is defined as T = r cross F, or just R X F. Basically, if you multiply the force by the distance of the force from the central point on the object you are trying to rotate, you have torque.
What is the torque speed characteristic?
the ratio of the relative speed of stator magnetic field with the speed of rotor, to the speed of rotor is defined as slip. where as in torque slip characteristic is the graph between the speed of the rotor and the torque experienced on the rotor. in the case of induction motor, the torque decreases with the increase in the rotors speed. while in the case of sychronous motor, its different (you check out, because i just forgot about it!! keep smiling!
Why does applied torque not change at 90 degrees?
At 90 degrees, the applied torque remains constant because torque is defined as the product of the force and the distance from the pivot point, multiplied by the sine of the angle between the force vector and the lever arm. At 90 degrees, the sine of the angle is 1, meaning that the entire force contributes to the torque. Therefore, while the angle changes, the magnitude of the torque does not, as it is maximized when the force is applied perpendicular to the lever arm.
What term is defined as the size of the force multiplied by the distance through which force acts?
The term is torque. Torque is a measure of how much a force acting on an object causes that object to rotate. It is calculated by multiplying the force applied by the distance from the axis of rotation.
Why does a screwdriver allow you to turn a screw you couldn't turn by hand?
A screwdriver allows you to exert more torque on a screw. Torque is defined as the product of the force exerted and the distance from the center of rotation. Torque is essentially a rotational force. It is simple to increase torque, simply increase the distance from the center that the force is being applied, and there is greater torque without increasing your effort. The handle is made to be wide, so that a greater torque can be exerted. It is also much easier to grip a screwdriver than it is to grip a screw. That also plays a factor.
Is it possible to calculate the torque acting on rigid body without specifying the axis?
Not at all possible. Torque defined as the moment of the force about a point or an axis of rotation. Torque tau vector = radius vector x Force vector. Radius is to be measured only from a given point or given axis. Hence axis in very important
Why clock wise torque is negative?
Clockwise torque is negative because it causes an object to rotate in the opposite direction as the conventionally defined positive direction. When a torque is applied clockwise, it produces a rotational motion that is deemed negative in terms of the reference frame used to define positive rotation.
